AI总结:

提出检测新闻文章中有害议程的新任务,发布NewsAgendas数据集,并证明可解释系统能有效识别有害议程且性能媲美黑盒模型。

摘要:

网络上的操纵新闻是一个日益严重的问题,需要使用自动化系统来遏制其传播。我们认为,尽管错误信息和虚假信息检测已被研究,但在检测新闻文章中有害议程这一重要的开放性挑战上,一直缺乏投入;识别有害议程对于标记具有最大现实危害潜力的新闻活动至关重要。此外,由于对审查制度的切实担忧,有害议程检测器必须是可解释的才能有效。在这项工作中,我们提出了这一新任务,并发布了NewsAgendas数据集,包含用于议程识别的标注新闻文章。我们展示了可解释系统如何在此任务上有效,并证明其性能可与黑盒模型相媲美。

英文摘要:

Manipulated news online is a growing problem which necessitates the use of automated systems to curtail its spread. We argue that while misinformation and disinformation detection have been studied, there has been a lack of investment in the important open challenge of detecting harmful agendas in news articles; identifying harmful agendas is critical to flag news campaigns with the greatest potential for real world harm. Moreover, due to real concerns around censorship, harmful agenda detectors must be interpretable to be effective. In this work, we propose this new task and release a dataset, NewsAgendas, of annotated news articles for agenda identification. We show how interpretable systems can be effective on this task and demonstrate that they can perform comparably to black-box models.
